with Intel 82573L Chipset Ethernet Gigabit Desktop PCIe Network Card Controller Adapter 10/100/1000M

UPDATED:I'm an idiot. Card works. Both interfaces work. pfSense is plenty happy with it. Made some pretty rookie technical mistakes. Works with Debian bullseye too.Original review:I use this in my pfSense box, the drivers are happy with the chipset, and both interfaces are recognized. Interface 1 (igb0) is perfectly good. Interface 2 (igb1) doesn't detect a carrier. I've tried multiple cables, rebooting, and other troubleshooting steps. Link issues are one thing but it can't even tell there's a cable plugged in... I'll have to end up getting another card for my project.

I bought this Ethernet PCI for replace My Ethernet at my Computer board. It work right out of the box. easy to install and compatible with Window's 10. the seller(Amazone) delivery on time as it promised. Thank.Minh Ngo

I was a little nervous about getting this card since the obvious "english as a second language" description made it seem like maybe it was but maybe it wasn't, but maybe it was running an intel chip and because of the reviews reporting non-intel chips. However, when I installed it in my truenas server to FINALLY replace the on-board garbage(realtek, yes, I should have read the section on compatible NICs when building the thing), the system booted right up and even presented the intel bios prompt for each chip/port on the card. I still wasn't 100% convinced so booted a live linux distro to see what the card actually reported for its chips. It's a dual card and both chips came up intel. Now that isn't to say they aren't couterfeit. China has proven it knows no boundaries when it comes to that, even going as far as hacking chips to present seemingly genuine identification/specs. I did do a sort of stress test after booting back into truenas by copying ~1tb of data and the transfer held steady at 103-105MB/s (big B for byte, not Mb/s for bit), which is satisfactorily close to the gigabit rating of my network. I also streamed on 2 devices at the same time from plex running on the server. It didn't drop once. The on-board garbage would regularly drop out with less than half that throughput. We'll see how it stands up over time though. Will update if anything changes. I'll also update if I ever get around to upgrading the rest of my network for higher speed and/or to handle aggregation so I can test that feature properly.

While unlikely to be an issue for most home applications, a chinese network card is probably a no go for many places due to potential security concerns. I use it for my home server that host docker containers for media centers, HVAC, and some small home automation and web services, it's enough for me and I might consider putting it on a VLAN later. Works great with VMware ESX8

This is NOT a 64-bit PCI-X card, it is a 32-bit PCI card that will WORK in a PCI-X slot, but will then limit your PCI-X buss to legacy PCI buss speeds.Perfectly fine for a legacy PCI slot but will never reach full gigabit ethernet speeds even using just a single channel."COMPATIBLE" should be the headline for this product. PCI-X compatible. Gigabit ethernet compatible.I can't wait to find out how "compatible" the drivers are.

The product was exactly as described - It is indeed a PCI card, not a PCI-E, as many reviews stated. It slipped into a PCI slot on my ASUS motherboard, and when I rebooted, provided me with two additional gigabit ethernet ports. My fiber internet connection went from 100 mbs, to around 600 mbs immediately.Thanks!

For the money, this Intel based chip was an excellent buy. I used it for a linux router and was concerned about driver support. Needless to say it just purrs along and has improved the i/O of the router. Thanks for the excellent product.

I have several of these, the Intel chipset is great but the cards themselves seem to burn out -- had one cease functioning after only 3 months and another in a different machine after about 8 months.
